LEVEL Specification of Letters Patent.

Patented July 16, 1918.

Application filed January 26, 1918. Serial No. 218,961.

To all whom it may concern:

Be it known that I, PAUL Boone, a citi zen of the United States. residing at Bethalto, in the county of Madison and State of Illinois, have invented new and useful Improvements in Levels, of which the followin is a specification.

This invention relates to a level, and more particularly to means for illuminating a level which may be otherwise of the stand ard type.

One of the objects is to provide an illu minating device comprising an electric lamp mounted beneath the level proper and within the bod portion or structure within which the evel is mounted, this lamp being supplied with current by a cell of any commercial type. and of suitable capacity for the purpose.

A further object is to provide certain means of novel construction for mounting the lamp and providing for the electrical connections thereof.

With the foregoing and other objects in View, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is a view in longitudinal section.

Fig. 2 is a transverse section on line 2-2 of Fig. 1.

Fig. 3 is a perspective view of a lamp su portin member.

lihe bo y portion is designated. 10 and is provided with a recess 12 receiving a battery 13, the terminals of the battery being designated 14 and 15. One wall of the recess 1.- is provided with a metallioplate 16 against which the terminal 14 of the battery is pressed. This plate 16 is in electrical communication with one terminal of the lamp 20 through wire 21 and resilient plate 22. The other terminal 15 of the battery may be laced in communication with the end of wire 24 leadin to the lamp base, this connection being siown at 25. Normally the terminal 15 of re ilient ma terial is out of engagement with wire 24 but may be placed in engagement therewith when pressure is exerted on ,element 15.

The resilient plate 22 is provided with a centrally depressed portion 26 for receiving the end of the lamp base and forming electrical connection with the terminal 27 of the lamp. Plate 22 includes deflected portions 23 and outwardly extending members 28 engaging slots 29. v

The recess 30 within which the lamp and plate 22 are mounted communicates by means of an opening 32 with a longitudinally extending channel 33 within which the level proper is mounted, this level being designated 34. Beneath. plate 22 is a cushioning member The recess or opening 32 is of such cross section that the surface of the lamp will engage the edges of the walls thereof and the resilient member will hold the lam) in engaged position, electrical contact eiug maintaim-d with the terminal 27 as indicated. if desired an aperture 37 may be provided in plate for engaging terminal 27.

A plate 40 closes the recess within which the battery is located, and the battery may be merely slipped into position with one terminal 14 in engagement with plate 16. The plate or cover member over the level 34 is designated 42.

lVhat is claimed is:

1. In a device of the class described, a body portion, a leveling device mounted therein, said body portion being provided with a recess below the leveling device and with an opening communicating with the recess and located below the leveling device, a lamp within the recess and engaging the walls of the opening, a resilient contact member comprising a plate mounted in the recess and engaging one terminal of the lamp, said plate extending beneath the lamp and exerting upward pressure thereon to retain the lamp in engagement with the edges of the opening, a cushioning member beneath the plate, a battery, means for connecting one terminal of the battery with the plate and means for connecting the other termlnal of the battery with the base of the lamp.

2. In a device of the class described, a body portion, a leveling device mounted therein, said body portion being provided with a channel accommodating the leveling device, an opening in the body portion constituting a recess below the channel, an opening between the opening first named and said channel, a lamp located within the opening or recess first named, means for holding the lamp in position and affording electrical connection therewith, said means comprising a deflected resilient plate member Elvin? a downwnrdl bent central portion and eterally exten ing engaging portions, the central portion contacting with 5 one terminal of the lamp, a cushion member mounted beneath the central portion, a battery, a plate member adjacent to one end of the battery and engaging one of the terminals thereof, means for connecting said plate member with the plate first named, and means for connecting the ozher terminal of the battery at times with the base of the lamp.

In testimony whereof I afiix my sign:\

ture.
